I built my own shed and i used some tanalised redwood tongue and groove barrel board, I have also the finished it in an oil based paint (creocote to be exact) its looks great!The only issue is now after about 1 - 2 months the boards seem to be developing gaps as the tongue and groove come apart. See photo: http://ift.tt/2w8iXrC Any idea why this is happening? Is the wood shrinking as it dries out etc & how can i fix this? Will this be a case where i need to remove the cladding and relay it? via /r/DIY http://ift.tt/2gfDR2F
